rear does not restore permissions and links if use of rsync to backup with a user other than root

Issue

• With a configuration to backup with rsync, with a user other than root:

  BACKUP_URL=rsync://rearuser@192.168.122.220/home/rearuser/rear/
  

• During the restore, all links are replaced by files: (/bin /lib ...):

• While it should restore the permissions and the links:

  lrwxrwxrwx.   1 root root    7 Apr 23  2020 bin -> usr/bin
  lrwxrwxrwx.   1 root root    7 Apr 23  2020 lib -> usr/lib
  lrwxrwxrwx.   1 root root    9 Apr 23  2020 lib64 -> usr/lib64
  lrwxrwxrwx.   1 root root    8 Apr 23  2020 sbin -> usr/sbin
